It’s just that I didn’t know, and my recollection is that Debian doesn’t
have -dbg packages for every package.

I see what you mean, but again, that’s not how it works, and I would
argue that it’s not desirable.
To move forward, a possible action would be to try to have ‘outputs’
default to '("out" "debug") and see (1) how much breaks, and (2) how
much space.
Would you like to give it a try?
Thanks,
